Clamping coupling

作者: Published: 2020-01-18

The characteristics and application of the clamping shell coupling: no compensation performance, no buffer or vibration reduction, convenient assembly and disassembly, simple structure, complicated shape, poor craftsmanship, and low balance accuracy.It is suitable for stable load and low speed conditions.

Note: JQW type is a clamp shell coupling is a JQ clamp shell coupling with a message suspension ring to avoid repeated axial positioning. It can be used in a single pivot frame.

Note: The other dimensions of the suspension ring and the shaft end are the same as those of the same shaft diameter of the JQ type clamp shaft.

● The clamping shell coupling uses two axially split clamping shells, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface, and the flat key is used as an auxiliary connection .

●When assembling and disassembling the clamp housing coupling, the shaft does not need to move axially, so the assembly and disassembly are very convenient. The disadvantage of the clamp housing coupling is that the accuracy of the axis of the two shafts is low, the structure and shape are more complex, and the manufacturing and balance accuracy Low, only suitable for low speed and stable load occasions, usually the maximum outer edge linear velocity is not more than 5m/s, when the linear velocity exceeds 5m/s, balance verification is required.

●In order to improve the balance, the bolts should be installed between the positive and the inverted phases.Jacketed couplings do not have axial, radial and angular compensation performance.

●The characteristics of the vertical clamp coupling are similar to those of the clamp coupling, simple structure, easy to assemble and disassemble, suitable for low-speed (maximum circumferential speed of 5M/S), no impact, and stable vibration load occasions. Used for the connection of vertical shafts such as agitators.
